Letting without a licence: the fines in the Balearics
Letting a property to tourists in the Balearics without the required licence is a serious administrative offence, sanctioned with fines that run from tens of thousands of euros upwards and that apply to the owner regardless of who managed the booking.

The short version
- Fines for unlicensed tourist letting start in the tens of thousands of euros.
- The licence number must appear in every advertisement.
- Advertising without a valid number is itself sanctionable.
- Inspectors use listings, guest registers and neighbour complaints.
This is the area where a foreign owner is most likely to break the rules without realising it, and where the consequence is measured in 5 figures rather than a warning letter.
What needs a licence
Letting a dwelling to tourists for short stays as a commercial activity requires registration and a licence number issued by the regional authority. The requirement applies to whole dwellings marketed for holiday stays, and the availability of licences is capped and zoned, so in some areas and for some property types no new licence can be obtained at all regardless of what the property is like.
| Point | Requirement | Consequence if missing |
|---|---|---|
| Licence number | issued by the region | serious offence |
| Number shown in adverts | compulsory | sanctionable in itself |
| Guest register | sent to the authorities | separate offence |
| Community consent | where statutes require | civil action |
| Tourist tax collection | per person per night | tax liability |
| Income declaration | rental income | tax penalties |
| Fine range | serious to very serious | tens of thousands upwards |
How it is detected
Systematically, not by chance. Listings are monitored and cross checked against the register of licensed properties, platforms are required to cooperate, guest registration data is matched, and neighbour complaints trigger inspections. An owner letting 8 weeks a year through a platform with no licence number in the listing is visible from a desk, and the advertisement itself is the evidence.
The community dimension
Separately from the regional licence, the community of owners may restrict or prohibit tourist letting in the building through a statutory amendment adopted by the required majority and registered. A licence from the region does not override a valid registered restriction. Before buying with letting in mind, both questions must be answered: is a licence available for this property, and does the community permit it.
Checking both takes an email to the administrator and a search of the regional register, and both should precede any offer.
If you already let without one
Stop advertising, take down the listings, and take advice before any inspection arrives. Regularising is sometimes possible where the property and the zone qualify, and voluntary regularisation is a materially better position than responding to a file already opened. Continuing to let while applying is not a defence, since the offence is the activity, not the absence of an application.
The arithmetic explains why the risk is not worth taking. A property letting 12 weeks a year at 1,400 € a week turns over 16,800 €, while a single serious penalty runs into the tens of thousands of euros. Add the tax on undeclared income for the last 4 years and the exposure exceeds several seasons of turnover.
Detection is systematic rather than accidental. Listings are cross checked against the licence register, guest registration data is matched and neighbour complaints trigger inspections. An owner letting 8 weeks a year through a platform with no licence number in the listing is visible from a desk in under 5 minutes, and the advertisement itself is the evidence.
The numbers behind the risk are simple. A property letting 12 weeks a year at 1,400 € a week turns over 16,800 €, while a single serious penalty runs into the tens of thousands. Add tax on undeclared income for the last 4 years at rates of 19 or 24 per cent, plus surcharges, and the exposure passes 3 or 4 seasons of turnover. Against that, obtaining a licence where places exist costs a few hundred euros in fees and an energy certificate at 80 € to 250 €.
